I bought it from a guy that heated his house with it, I just heated my garage. It has a box on top to direct air into the duct work of a house, I just let it blow all over the garage.
Some of the fire brick on the back wall is broken from tossing logs at it, I was going to glue them together with [flue pipe mortar] don't know what it's called. Replacements are available. I have a manual with a parts list and Dealers.
I don't really need anything, but swaps etc. listened to.
Located near Albany, NY
